QuickShift® Transmissions
You've Got To Feel It To Believe It
You've Got To Feel It To Believe It
No other marine transmission in the world shifts as fast and smooth as the Twin Disc QuickShift, yet it provides amazing slow speed control at one knot or less. With its patented, completely internal and integrated clutch actuating system, QuickShift instantly delivers cushioned torque to the driveline when shifting from neutral to anywhere from full ahead to full reverse.
Express Joystick System®
No lagging. No lugging. No lurching. No clunking.
No lagging. No lugging. No lurching. No clunking.
The EJS smoothly and simultaneously actuates and controls engines, transmissions, propellers and thrusters. With no hesitation, all propulsion components actuate proportionally to the pressure you exert on the joystick to move your vessel precisely where you want, at the speed you intend. You can point the bow in any direction without moving from a fixed position. You can crab the boat diagonally or slip it straight sideways. You can even rotate it 360° on its axis
Arneson® Surface Drives
Their design reduces underwater drag by 50%
Their design reduces underwater drag by 50%
The ultimate in speed, maneuverability, efficiency & dependability.Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems. The only surfaces to contact the water are the propeller blades and a protective skeg. This results in higher overall speed, quicker acceleration and a better payload-to-power ratio. And 50% less drag significantly improves fuel economy while lowering operating costs.
Rolla™ Propellers
Highest efficiency & quality propellers world wide
Highest efficiency & quality propellers world wide
Since 1963 the name Rolla has been synonymous with the highest efficiency, highest quality propellers in the world. This means complete hydrodynamic engineering service, unique in the industry. Starting with a CFD analysis of the hull, including sea keeping, to the most sophisticated CFD propeller design methods for submerged and surface propellers. This integration of hull analysis and propeller design allows the most efficient solution to any performance and use profile given.
Trim Tabs
Stainless steel and Aluminum trim tab systems
Stainless steel and Aluminum trim tab systems
Trim tab systems are the result of decades of technological development with a continuous commitment to achieving best performance, stability control in any condition and better maneuverability of the boat. Trim tab systems are available in different models covering applications from 8 to 25 mt (37' - 110') for both displacement and planning hulls.
Thrusters
Electric and Hydraulic Thrusters
Electric and Hydraulic Thrusters
Major boat yards appreciate the compact design and easy installation of Twin Disc thrusters.
Reliable and high-performing, Twin Disc thrusters are suitable for applications from 6 to 40 mt (20' - 132').
Electric thrusters feature a reversible electric motor at a continuous current. A complete range is available for applications from 6 to 18 mt (20' - 60').
Hydraulic thrusters feature a double counter-rotating propeller and are available for applications up to 40 mt (131').

Dynamic Positioning Interface
Keeps supply vessels "on station"
Keeps supply vessels "on station"
The high-efficiency, high-performance combination of QuickShift® marine transmissions and EC300DP controls allows instantaneous, shockless, virtually constant forward and reverse shifting to keep supply vessels "on station" as directed by the craft's dynamic positioning system. Drivelines can execute directional reversals at variable torque levels more than 30 times per minute to hold station with the full requirements of the DP class.
MCD (Marine Control Drive)
Variable speed drive
Variable speed drive
The Marine Control Drive or MCD is available in a range of sizes with power capacity from 160 to 4500 kW (215 to 6035 HP) @ 1800 RPM. The MCD has proven its worth, particularly in tug applications, ice breakers, dredgers & fire fighting vessels. The system provides distinct operational advantages for any vessel requiring accurate positioning or a high degree of slow speed maneuverability while the main engine powers another action. There are 3 sizes with 5 models for each size.
Hydraulic Steering Systems
Hydraulic pumps and cylinders
Hydraulic pumps and cylinders
As a result of more than 50 years of experience, our steering systems are a synthesis of selected materials, innovative design and state-of-art technical solutions.
Conforming with "the Standard 94/25/CE", as amended by "the Standard 2003/44/CE", and also included in the Type Accepted of Program NMMA, the Twin Disc line of hydraulic pumps and cylinders covers any type of application: outboard, stern-drives and inboard systems for pleasure and commercial vessels.
